                                 2000 BONUS PLAN

PHILOSOPHY:

The Company believes that a portion of each employee's annual compensation
should be directly related to the Company's financial performance. The 2000
Bonus Plan is designed to motivate and reward employees for achieving certain
key financial results and, in the case of the Company's senior management,
certain business and strategic objectives. The Company believes that the
achievement of these goals and objectives is essential for the Company's success
and for the continued growth in shareholder value.

FINANCIAL MEASURE:

Operating income for 2000 determined in accordance with GAAP will be the sole
financial measure for the 2000 Bonus Plan for employees other than executive
officers of the Company. Executive officers will have operating income as a
financial measure for 75% of their bonus and other objectives for the remaining
25%.

Minimum operating income before bonus of $70M will produce 25% of the maximum
bonus. Maximum operating income before bonus of $85M will produce 100% of the
bonus. There will be a linear increase in bonus between minimum and maximum
operating income.

ELIGIBILITY:

All employees of Tekelec and its subsidiaries during 2000 are eligible to
participate in the 2000 Bonus Plan with the following exclusions:

          1. Commissioned employees
          2. Employees hired in 4Q of 2000

Employees must be employed by Tekelec or one of its subsidiaries on the date of
bonus payment to be eligible to receive a bonus payment under this Plan.

PARTICIPATION LEVELS:

The bonus payable to an eligible employee under the 2000 Bonus Plan is based on
a percentage of his/her calendar year 2000 actual earnings, excluding certain
payments (e.g., reimbursement for moving expenses, bonus payments from prior
year, stock option gains and similar payments). The maximum bonus percentage is
based on the position as listed below in the table.

MBO COMPONENT:

Twenty-five percent of the bonus for executive officers of the Company and the
Managing Director, Tekelec Limited (UK), will be linked to MBOs. The CEO and
officer will jointly set objectives at the beginning of the year. Evaluation of
these objectives will be made by the CEO by January 31, 2001.

Twenty-five percent of the bonus for the CEO will be linked to MBOs which will
be jointly set by the CEO and the Board of Directors. Evaluation of these
objectives will be made by the Board by February 15, 2001.

DISCRETIONARY BONUSES:

Discretionary bonuses may also be paid under the Plan but only if, in
management's view, the Company is able to pay a discretionary bonus without
materially adversely affecting the Company's financial results and special
circumstances exist. Consideration for such bonuses would be given for special
circumstances or achievements by a division, group, individual or perhaps
company-wide. With the advice and counsel of the Board of Directors, the CEO has
the authority to award discretionary bonuses to non-executive officer employees.
With regard to discretionary bonuses for executive officers, express approval of
the Board of Directors is required.
